TO ALL WHOM IT MAY CQNCERN:

Be it known that I, GEORGE W. BOWEN, of Fort Wayne, in the county of Allen, and State of Indiana, have p invented a new and improved Well-Borer; and that the following description, taken in connection withthe accompanying drawings hereinafter referred to, forms a full and exact 'specification of the same, wherein I l1 vc set forth the nature and principles of my said improvements, by which my invention may be distinguished fr m all others of a similar class, together with such parts as vI claim and desire to have secured to me by. Letters Patent. Y

' I The present invention lrelates to a tool or implement for the boring or sinking of wells in quicksand, orl for cleaning out wells, which tool is of sucha construction as to enable the work to be done with great rapiditjy,,A

facility, and safety, and inthe most satisfactory and perfect manner, as will be Obvious from the following detail' description Of the same, referencebeing hadto the accompanying plate of drawings, in which-- Figure 1 is a Viewl of thc under side or face of the boring-end of the tool, and

Figure 2 a central vertical section, taken in the plane, of the line :r x, iig. l.

A, in thevdrawings, represents the shank or stem of the tool, which at one end, C, is adapted to receive an extension-rod or handle, B, for lengthening or extending it out to bore a well of a greater or less depth; C, the boring-end of the tool, which is formed of a' circular-shaped disk or plate, D, around the periphery of which,. E, is a raised edge or rim, F, forming a box, G. .This disk D, at two points in radial lineswith its centre, H, is cut or slit from' a point, I, near its centre, to its raised edge F, with the sides of such slit turned or bent, theone up and with the other down in each case, leaving an opening or space, @between the two. The turneddown edges or sides of the slits to the disk are provided with sharp orcutting-edges, either by attaching a scpf arate steel blade thereto, or by properly sharpening the edges. The disk D is also perforated with small holes q. L, a centrepoint, upon the under side of disk D, on which the tool, as it is used,.turns.

In using the tool, if to bore, or sink, or clear out a well, it is inserted therein, and then turned around within the same, the dirt passing up through the openings formed by the turned up and down sides of the slits in the disk, into the box above the disk, by and in which it is removed as the tool is drawn out of the well. The perforations inthe disk allow the.waterto pass through, if any there be in the well, and by giving to the turnedup edges ofthe slits a sulicient spring they can `yield to any large substance passingthrough the slits.

Having thus described my invention, I claim as new, and -desire to secure by Letters Patent- 1. The circular plate D, for well-cleaning, when provided with holes a, for the purpose of allowing the escape of water from the dirt or sandheing lifted from the well, as herein set forth for thcpurpose specied.

' 2. The plate D, having spring cutting-edges, all formed in one piece, and provided with holes a, as and for the purpose specified. v

3. The application of the ropes toI the plate D for the purpose of elevating the tool from the well, as and for the purpose speied.

4. The tool for cleaningwells, constructed as described, consisting of the perforated disk D, having spring cutting-edges, surrbnnded by the rim F, and provided with adjustable handle A B, as herein shown and described.
